I love these coil overs ride is good quality is good have had them for about 8 months now and haven't had any problems out of them from the drag strip to the auto cross track and I like the fact that the dampening adjusters are removable

Let me put it this way, a new Porsche Cayman S with stock suspension is a rougher ride than these ISC coilovers, on a softer setting.
Great set of coilovers!
Excellent customer service from ISC!
